碩士 === 臺灣大學 === 物理研究所 === 95 === NTUHEP group take part in the CMS (Compact Muon Solenoid) experiment at the LHC (Large Hadron Collider). The LHC is a proton-proton collider and its center of mass energy is 14 TeV. It will begin running in the end of 2007 or in the early 2008. In the master thesis, I will introduce • the LHC, the CMS and the preshower detector; • the purpose and design of the preshower system motherboard (SMB); • the purpose and design of the SMB tester boards (SMB TB); • the connection tests of SMBs and the test program; • the test result of SMBs. Finally, I will do some simulations of the decay modes which have the largest cross-section of p-p collision and find what are measured in the preshower detector.
